Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-aromatic phthalonitrile analogs
Only aromatic nitriles specifically listed fall here; aliphatic isomers go to 'other' aromatic category.
If pre-reacted into dye intermediate form
Synthetic organic products used as luminophores exclude from Chapter 29 per chapter note (g).
If classified primarily by cyclic hydrocarbon structure
Dinitriles sometimes argued under cyclic hydrocarbons if nitrile function secondary.
